COLUMBUS (AP) — Coroner’s offices in central Ohio are struggling to fill positions as caseloads increase and more doctors seek employment in the private sector.

The Columbus Dispatch reported that the number of cases Ohio coroners and medical examiners are dealing with has been on the rise amid a drug-overdose crisis sweeping the state.

The Franklin County office performed 1,778 autopsies in 2015, up from 1,420 in 2014. That number is expected to jump to 1,854 in 2016. Records show the office has four forensic pathologists and one chief deputy coroner.

The newspaper reported that offices in Ohio are facing the risk of losing national accreditation due to a stagnant pool of pathologists and increasing cases. Officials say losing accreditation could damage their credibility when testifying in court.
